3-5 Power Management Setup

This option displays a table of items which lets you control the power
management of the system. Modern operating systems take care of
much of the routine power management. This mainboard supports ACPI
(advanced configuration and power interface).

This system supports three levels of power-saving modes; doze mode,
standby mode, and suspend mode. Standby mode uses less power than
doze mode and suspend mode uses the least power.

Power Management

This item acts like a master switch for the power-saving modes and
harddisk timeouts. If this item is set to Disabled, all the power-savings
modes are disabled. If this item is set to Max Saving, doze, standby,
and suspend mode, and the harddisk powerdown will occur after a
timeout of 1 minute. If this item is set to Min Saving, doze, standby,
and suspend mode will occur after a timeout of 1 hour. The harddisk
powerdown will occur after 15 minutes. If the item is set to User Define,
you can insert your own timeouts for the power-saving modes and
harddisk powerdown.

Default:User Define

Allow users to set the period counting from the beginnings of Doze
to enter this mode. BIOS will set CPU in stop clock state and stop
CPU fan to get an optimized power saving rate. Besides video will
be turn off in entering this mode or follows standby status.

Default:Disable

3-6 PnP/PCI CONFIGURATION Setup

This option displays a table of items that configures how PNP (Plug
and Play) and PCI expansion cards operate in your system.

PnP OS Installed

Set ‘Yes’ to bypass BIOS PnP device initial except of boot device.
PNP OS will do these PnP devices residently. If set this item to
'No', BIOS will handle all PCI/PnP devices.

Default:No

Resources Controlled By

Basically, BIOS will allocate the IRQ/DMA resources automatically
for these PnP/PCI and onboard devices. The exception might be
encountered when legacy ISA devices are installed, which occupies
resources that BIOS can’t know.Therefore, this option is for BIOS
to know in advance what IRQ/DMA is occupied by legacy ISA devices
if “Manual” is selected.

Default:Manual

Chapter 3-17

LXB/EXB User's Manual

Reset Configuration Data

Once ‘Enabled’ is selected, BIOS will turn it ‘Disabled’ again in
next Boot. The option is for clearing ESCD data. The only reason
to clear is the data loosing the confidence. The engineering test is a
good reason to change the default setting.

Default:Disabled

IRQ/DMA assigned to

The option provides IRQ/DMA resources assigned Legacy ISA or
PCI/ISA PnP card

Default: IRQ3~4 => Legacy ISA

Others => PCI/ISA PnP

PCI IDE IRQ Map To

This is a complement for the case that an ISA or PCI add-on IDE
card are installed. Since most of PCI add-on IDE cards are not PCI­compliant, a location and INT# inputs are necessary for
acknowledging to BIOS.

Default:PCI-Auto

This option defines the rest of Legacy ISA Cards used memory will
be used by PnP card.

Default:N/A
